Grok Imagine Image Pro

# Grok Imagine Image Pro

API Key: `$XAI_API_KEY` (already configured) Save dir: `~/.openclaw/media/` (resolves to `/data/.openclaw/media/` — allowed for Telegram sending)

Available Models

• `grok-imagine-image` — standard quality, faster
• `grok-imagine-image-pro` — higher quality (default for generation)

1. Image Generation

```bash curl -s https://api.x.ai/v1/images/generations \ -H "Authorization: Bearer $XAI_API_KEY" \ -H "Content-Type: application/json" \ --data '{ "model": "grok-imagine-image-pro", "prompt": "<PROMPT>", "n": 1, "response_format": "b64_json" }' | python3 -c " import json, sys, base64, os, time os.makedirs(os.path.expanduser('~/.openclaw/media'), exist_ok=True) r = json.load(sys.stdin) ts = int(time.time()) for i, img in enumerate(r['data']): img_data = base64.b64decode(img['b64_json']) fpath = os.path.expanduser(f'~/.openclaw/media/generated_{ts}_{i}.png') with open(fpath, 'wb') as f: f.write(img_data) print(fpath) " ```

Aspect Ratios

Add `"aspect_ratio": "<ratio>"` to the JSON body. Supported values:

| Ratio | Use case | |-------|----------| | `1:1` | Social media, thumbnails | | `16:9` / `9:16` | Widescreen, mobile stories | | `4:3` / `3:4` | Presentations, portraits | | `3:2` / `2:3` | Photography | | `2:1` / `1:2` | Banners, headers | | `auto` | Model picks best ratio (default) |

Batch Generation

Set `"n": <count>` (1-10) to generate multiple images in one request.

2. Image Editing / Style Transfer

Edit an existing image by providing a source image plus an edit prompt. Uses the same `/v1/images/generations` endpoint with an added `image_url` field.

Do NOT use `/v1/images/edits` with multipart — xAI requires JSON.

IMPORTANT: For local files, use Python to build the payload JSON file, then curl with `@file`. Inline base64 in curl args causes "Argument list too long" for images >~100KB.

NOTE: This is NOT true image editing — the API generates a new image inspired by the source. It cannot make pixel-precise edits (e.g. changing only a car's color while keeping everything else identical).

Edit from local file (recommended approach):

```bash python3 -c " import json, base64 with open('<SOURCE_PATH>', 'rb') as f: b64 = base64.b64encode(f.read()).decode() payload = { 'model': 'grok-imagine-image', 'prompt': '<EDIT_PROMPT>', 'image_url': f'data:image/png;base64,{b64}', 'n': 1, 'response_format': 'b64_json' } with open('/tmp/img_edit_payload.json', 'w') as f: json.dump(payload, f) print('Payload ready') " && \ curl -s https://api.x.ai/v1/images/generations \ -H "Authorization: Bearer $XAI_API_KEY" \ -H "Content-Type: application/json" \ -d @/tmp/img_edit_payload.json | python3 -c " import json, sys, base64, os, time os.makedirs(os.path.expanduser('~/.openclaw/media'), exist_ok=True) r = json.load(sys.stdin) img_data = base64.b64decode(r['data'][0]['b64_json']) fpath = os.path.expanduser(f'~/.openclaw/media/edited_{int(time.time())}.png') with open(fpath, 'wb') as f: f.write(img_data) print(fpath) " ```

Edit from URL:

```bash curl -s https://api.x.ai/v1/images/generations \ -H "Authorization: Bearer $XAI_API_KEY" \ -H "Content-Type: application/json" \ --data '{ "model": "grok-imagine-image", "prompt": "<EDIT_PROMPT>", "image_url": "<PUBLIC_IMAGE_URL>", "n": 1, "response_format": "b64_json" }' | python3 -c " import json, sys, base64, os, time os.makedirs(os.path.expanduser('~/.openclaw/media'), exist_ok=True) r = json.load(sys.stdin) img_data = base64.b64decode(r['data'][0]['b64_json']) fpath = os.path.expanduser(f'~/.openclaw/media/edited_{int(time.time())}.png') with open(fpath, 'wb') as f: f.write(img_data) print(fpath) " ```

Style Transfer Examples

• Use editing with a style prompt, e.g.:
• "Render this as an oil painting in impressionist style"
• "Make this a pencil sketch with detailed shading"
• "Convert to pop art with bold colors"
• "Watercolor painting with soft edges"

3. Sending to Telegram

``` message tool: action=send, channel=telegram, target=<id>, message="<caption>", filePath=~/.openclaw/media/<file>.png ```

• Always include `message` field (required even for media-only sends)
• Allowed media paths: `/tmp/`, `~/.openclaw/media/`, `~/.openclaw/agents/`

Notes

• Do NOT pass `size` parameter — returns 400
• Aspect ratio: pass `aspect_ratio` in JSON body (not `size`)
• Editing: use `image_url` field in the generations endpoint (NOT the edits endpoint with multipart)
• Always use `"response_format": "b64_json"` — URL format returns temporary URLs that often 403
• For large images: build payload with Python → save to `/tmp/` → curl with `@file` syntax
• Max 10 images per request
• Images are subject to content moderation
• Editing is style-transfer/reimagination, NOT pixel-precise inpainting
